Get sorted folders by size when getting them from outlook

Question

I use the following code to retrieve all folders from outlook :

 public void getFolderPath()
    {
        try
        {
            OutLook.Application oApp = new OutLook.Application();
            OutLook.NameSpace oNS = (OutLook.NameSpace)oApp.GetNamespace("MAPI");
            oNS.Logon(Missing.Value, Missing.Value, false, true);

            foreach (MAPIFolder folder in oNS.Folders)
            {
                GetFolders(folder);
            }

            Marshal.ReleaseComObject(oApp);


        }
        catch (System.Exception ex)
        {
            MessageBox.Show(ex.ToString());
        }
    }

This show me all folders from top to bottom as listed in OutLook , is there a way that i can show them or go trough them i ascending order by their size.

Something similar to :

foreach (MAPIFolder folder in oNS.Folders.sortbysize())
        {
            GetFolders(folder);
        }
